IEUEL-SAVIN G APPLIANCE FOR INTERNAL-COMBUSTION ENGINES.

Speo1flcatlon of Letters Patent. Patented N V. 25,' 1919.

Application filed November 16, 1918. Serial at. 262,916.

Be it known that I, HALL zen of the United States, residing at Chicago, in the county of Cooka nd State of Illinois, have invented new and useful Improvements in Fuel-Saving Appliances for Internal-Combustion Engines, of which the motor.

following is a specification. I

This invention relates to devices a plicable' to internal-combustion engines an designed for the purpose ofefi'ecting a savin of fuel, the resent device being one whic utilizes'the 0t oily va ors present in the crank case of the engine by leading the same to the air-intake of 'thecarbureter to be taken up with the regular fuel charges and delivered to the engine cylinders.

The invention has for its object to. rovide a very simple and efficient device 0 the kind stated, and to this end it consists in a novel combination and arrangement of parts to be hereinafter described and claimed.

In order that the invention may be better understood, reference is had to the accompanying drawing, forming a part of this specification.

In the drawing,

Figure 1 is an elevation showing the application of the invention, and

Fig. 2 is a sectional detail of the device.

Referring specifically to the drawing 5 denotes the breather pipe which 0 ens into the crank case 6 of the engine s own'in outline in Fig. 1. The invention is applicable to all internalscombustion enginesdesigned for motor vehicles and having a closed crank case. The drawing shows the invention applied to the well known Ford The carbureter is shown at 7 and the intake manifold at 8. These parts are arranged and operate in the usual manner,

except that the air supply of the carburetor is taken from the crankcase through a connection between the breather pipe and theair-intake of the carburetor. This connection comprises the following parts:

A vertical tube 9 fits sniigly in the inlet' is connectedby a flexible pipe or tubing 11 to the air-intake of the carburetor 8, as shown in Fig. 1. Before applying'the tube 9, the usual cap which seats over the inlet.

Gooowm, a citicurls or It will be evident fromthe foregoing that the suction at the air-intake of the carbu- 'reter 8 draws the gases and oil-impregnated air from the interior of the crank case through the breather pipe 5, the tube 9, the

branch 10 and the connection 11. These vapors are therefore utilized and mixed with the fuel charges delivered by the carbureter, 1

resulting in a saving of fuel. If there is leakage of compression past the piston rings into the crank case, the same is not lost as the vapors are withdrawn by the carbureter and again delivered to the engine 0 linders with the hot oily vapors generate in the crank case.

As the vapors drawn into the carbureter 8 may contain oil in an unva orized state, the branch '10 is provided wit an oil separator composed of a series of inclined baffle plates or partitions extendin alternately from the top and the bottom 0 the branch,

the top partltion being denoted by the reference character 14, and the bottom ones by the reference character 15. The lower ends of the top partitions have forward bends -16, and the upper ends of the bottom partitions have forward and downward bends 17 more ironounced than the bends 16. Be-

neath t e partitions are oil collecting pockets 18 fitted with drain cocks 19.

The oil entrained in the vapors passing through the branch 10, u on striking the partitlons 14 and 15 is de ected by the latter into the pockets 18 which latter can be emptied at suitable intervals uponopenmg .the cooks 19. -By the staggered arrangement of the partitions the vapors are made to take a tortuous path through the branch, resultin in a more efficient separation. The

%)ends at the extremities of the partitions also serve to increase the efliciency of the separator by deflecting and retarding the passage of the va ors.

In the tube 9 is a ongitudinal partition 20, located in the mid'dlethereof and divid:

ing the same into two chambers denoted by the reference characters 21 and 22, respectively. The partition 20 starts from the top of the branch 10 and extends down directly into the branch.

the air intake of the carbureter 8 draws the through the tube, its lower end extending a short distance from the lower end of the latter. Both endsof the tube 9 are open, and its upper end is fittedwith a screen 23 to exclude dust and dirt. The chamber 21 is in direct conununicati'on'with the upper end of the tube 9 and opens at its lower end into the breather pipe 5. The chamber 22 is not in direct communication with the chamber 21, but opens at one end into the breather pipe 5 and at its other end into' the branch 10, this being for the purpose of preventing the outside air from passing The suction at vapors in the crank case through the chamber 22, and these vapors are mixed with air entering the chamber 21 through the upper end of the tube 9.

The appliance is very simple,-and inexpensive, and'it can befreadilv mounted in place for use withoutany' changes'in the carbureter or other parts.

I claim: The combination with the carbureter and the crank case of an internal-combustion en gine, said crank case having a breather ipe;

the e communication between the outside air and the breather pipe.
